Windows 10: Win 10 21H1 update black screen for 6 minutes after login

After updating to Win 10 21H1 version, every time I turn on my system and connect, the screen goes black for about 6 minutes. It happened only after the system was updated to version 21H1.

Windows 10 - black screen with cursor after login

Hi WB,

I had a similar Black Screen problem I documented on this site and solved my problem.

The following may not help you but it fixed my problem.

MS responses in this forum are formulaic based upon keywords IMHO.

Try this:

• Login to Windows 10 and if you have a Black Screen, wait about 15 minutes (to be sure) before you get bored and decide to reboot. I've had the experience that after a MS software update that when the computer reboots, it sits there with a Black screen
  for a while. I've seen this a few times and if I walked away and come back 30-60 minutes later, it often is working.
• Alternatively, (I've seen this several times), at the Black Screen: turn off your monitor and after a few seconds turn it back on. My display card ( an Nvidia variant I think ) sometimes has trouble upon boot. When I cycle the monitor off/on, the display
  comes up and works.
• The following solution to a Black Screen problem was discovered after I upgraded to Win 10 from Win 8.1 (2 weeks later). MS had pushed some update which conflicted with a Startup program and then the startup list was aborted and the S/W was left in an
  unstable state. Try this:
  • After login and encountering Black Screen, try CTRL-ALT-DEL. This should bring up a menu (if windows is partially running and you don't have a display driver issue). If you get the menu, select Task Manager. This brought up a single white window in the
    middle of my black screen. Expand the window by dragging the corner and you should see the task list. If you do, proceed to the next step. Otherwise, bail out. This solution will not work for you.
  • Task Manager has now integrated the capabilities of the old msconfg.exe (if you remember that). Go to the Start Up tab and you should see a list of programs that will execute upon login. Most are enabled. Some may be disabled. Try disabling non-MS startup
    programs. Save and restart.
  • There is an element of educated guesswork here but for me this solved my problem and upon the next boot, I was able to see the desktop and navigate the menus.
  • If this works, your next task is to go back to Task Manager, Startup, and re-enable the entries you disabled one by one and reboot until you discover the offending program.

I did not need to re-install Windows or re-install device drivers as seems to be the popular suggestions.

Hope some of this helps. Good luck.

 

Black Screen Isuue in Window 10

Hi kashish,

I would appreciate you for trying troubleshooting steps.

To understand the issue better, I request you to answer few questions:

• Does black screen appear when you before user login’s or after user has logged in ?
  
• Does black screen appears when you lock your pc?

This problem occurs because of a change in the behavior of Win Logon and Logon UI. This change introduces the potential for the deadlock.

I would also suggest you to install all the updates available for the system and check if it helps.

Follow the Below steps:

• Type settings in the Search area on the taskbar and select Settings
• Select Update and Security.
• Click on Windows Update and select Check for Updates

Keep us posted with the status of the issue. We’ll be glad to assist if you need further assistance.

Thank you
